Yesterday I got three red eyed tree frogs from petco. The third I have isolated because he is dark in color, lethargic, and his stomach is reddish so I am worried it's Red Leg. The other two seem healthy and are sleeping on the glass right now. One has a white tummy, the other is slightly off-color. I wasn't sure if this was because of Red Leg or his natural color.

Can they recover from this? Maybe I diagnosed wrong? Here are pictures of my apparently healthy frog, the second "off-color" tummy frog, and the dark frog, the tank, and everything.

What do you think?
